inappropriate content. Changed this to a smaller file about quantum
computers.

> [!NOTE]
> Update vector search limit-none tests to use local quantum/NLP files
and add `test_data/Quantum_computers.txt`, adjusting queries
accordingly.
>
> - **Tests**:
> - **Vector engine limit-none coverage**
(`test_vector_engine_search_none_limit`):
> - Replace `examples/data/alice_in_wonderland.txt` with
`tests/test_data/Quantum_computers.txt` and
`tests/test_data/Natural_language_processing.txt` across
`cognee/tests/test_chromadb.py`, `cognee/tests/test_lancedb.py`, and
`cognee/tests/test_pgvector.py`.
> - Update query to "Tell me about Quantum computers" and keep assertion
verifying no implicit `limit` (ensure `len(result) > 15`).
> - **Test data**:
> - Add `cognee/tests/test_data/Quantum_computers.txt`.

> [!NOTE]
> Standardizes vector search to accept `limit=None` (fetch all/count),
updates adapters/interface and retrievers, and adds tests plus minor
logging/doc assets.
>
> - **Vector search API**:
> - Change `limit` to `Optional[int]` in `vector_db_interface` and
adapters (`ChromaDBAdapter`, `LanceDBAdapter`, `PGVectorAdapter`,
`NeptuneAnalyticsAdapter`).
> - Behavior: `limit=None` fetches all/collection count; early-return on
`limit<=0`; minor logging copy/level tweaks; `PGVector` counts via
`func.count`.
> - **Retrievers**:
> - Switch internal calls to `limit=None` (`CogneeGraph`,
`temporal_retriever`, brute-force triplet search).
> - **Tests**:
> - Add `limit=None` coverage for ChromaDB, LanceDB (new suite), and
PGVector; assert results exceed default caps.
> - **Examples/Docs**:
> - Demo script prunes before run; add tutorial notebook and data
assets; remove one markdown article.
> - **Misc**: LLM utils demote a log line to `debug`.

Until now, limit=0 in vector search meant that there is no limit and we
should return everything. This caused confusion and errors, so now it is
reworked so that limit=None means no limit on the search. If someone
puts limit=0, there will be no results returned, as it makes more sense
and is less error prone.
